Thomas Friedman, and many others, think it is a sign of America's decline and some sort of failure of government will that other countries are building super-massive showcase infrastructure projects while we are not. They would take this chart as a sign of decline:

I disagree. This is a sign of growing maturity on the part of the United States. Many of these super-tall building projects make little economic sense, but are completed to validate the prestige of emerging nations, like teenage boys comparing penis sizes. Grown men are beyond that behavior, just as are grown-up nations. I discussed this in the context of rail a while back at Forbes. In that case, it seems everyone thinks the US is behind in rail, because it does not have sexy bullet trains. But in fact we have a far more developed freight network than any other country, and shift of transport to rail makes a much larger positive economic and environmental impact for cargo than for rail. It comes down to what you care about -- prestige or actual performance. Again choosing performance over prestige is a sign of maturity.**

The US had a phase just like China's, when we were emerging as a world economic and political power, and had a first generation of successful business pioneers who were unsure how to put their stamp on the world. So they competed at building tall buildings. Many of the tallest were not even private efforts. The Empire State Building was a crony enterprise from start to finish, and ended up sitting empty for years. The World Trade Center project (WTC) was a complete government boondoggle, built by a public agency at the behest of the Rockefeller family, who wanted to protect its investments in lower Manhattan. That building also sat nearly empty for years. By the way, the Ken Burns New York documentary series added a special extra episode at the end after 9/11 on the history of the WTC and really digs in to the awful crony and bureaucratic history of that project. Though Burns likely did not think of it that way, it could as easily be a documentary of public choice theory. His coverage earlier in that series of Robert Moses (featuring a lot of Robert Caro) is also excellent.

** I have always wondered if you could take this model further, and predict that once-great nations in decline (at least in decline relative to their earlier position) might not re-engage with such prestige projects, much like an aging male seeking out the young second wife and buying a Porche.

Update: Here is part of what I wrote on US vs. European and Japanese railroading, which I think is an absolutely awesome example of where the triumphalists like Friedman go wrong:

In particular, both Friedman and Epstein think we need to build more high speed passenger trains. This is exactly the kind of gauzy non-fact-based wishful thinking that makes me extremely pleased that these folks do not have the dictatorial powers they long for. High speed rail is a terrible investment, a black hole for pouring away money, that has little net impact on efficiency or pollution. But rail is a powerful example because it demonstrates exactly how this bias for high-profile triumphal projects causes people to miss the obvious.

Which is this: The US rail system, unlike nearly every other system in the world, was built (mostly) by private individuals with private capital. It is operated privately, and runs without taxpayer subsidies. And, it is by farthe greatest rail system in the world. It has by far the cheapest rates in the world (1/2 of Chinaâs, 1/8 of Germanyâs). But here is the real key: it is almost all freight.

As a percentage, far more freight moves in the US by rail (vs. truck) than almost any other country in the world. Europe and Japan are not even close. Specifically, about 40% of US freight moves by rail, vs. just 10% or so in Europe and less than 5% in Japan. As a result, far more of European and Japanese freight jams up the highways in trucks than in the United States. For example, the percentage of freight that hits the roads in Japan is nearly double that of the US.

You see, passenger rail is sexy and pretty and visible. You can build grand stations and entertain visiting dignitaries on your high-speed trains. This is why statist governments have invested so much in passenger rail â not to be more efficient, but to awe their citizens and foreign observers.

But there is little efficiency improvement in moving passengers by rail vs. other modes. Most of the energy consumed goes into hauling not the passengers themselves, but the weight of increasingly plush rail cars. Trains have to be really, really full all the time to make for a net energy savings for high-speed rail vs. cars or even planes, and they seldom are full. I had a lovely trip on the high speed rail last summer between London and Paris and back through the Chunnel â especially nice because my son and I had the rail car entirely to ourselves both ways.

The real rail efficiency comes from moving freight. As compared to passenger rail, more of the total energy budget is used moving the actual freight rather than the cars themselves. Freight is far more efficient to move by rail than by road, but only the US moves a substantial amount of its freight by rail. One reason for this is that freight and high-speed passenger traffic have a variety of problems sharing the same rails, so systems that are optimized for one tend to struggle serving the other.

Freight is boring and un-sexy. Its not a government function in the US. So intellectuals tend to ignore it, even though it is the far more important, from and energy and environmental standpoint, portion of transport to put on the rails. In fact, the US would actually probably have even a higher rail modal percentage if the US government had not enforced a regulatory regime (until the Staggers Act) that favored trucks over rail. If the government really had been asleep the last century, we would be further along.
